That's exactly how Consumer Society is meant to work: people buy shit to fill and unexplained void within them which turns out not to actually do so for long hence you have to buy more shit to fill that void.

Oh, and by the way, meanwhile advertising is, ALL THE TIME, blasting you with the idea that you're somehow not really happy and co plete without buying someshit (just look at all the happy people with their friends having fun around their MegaGrill 2000 ^TM^)
